YOKOGAWA PW482-10 Power Supply Module
1. Product Description
The YOKOGAWA PW482-10 is a high-performance industrial power supply module designed for critical automation systems, delivering stable AC/DC power conversion for PLCs, DCS systems, and field devices. Manufactured by Yokogawa Electric Corporation, the PW482-10 supports a wide input voltage range (100–240V AC) and provides dual DC outputs (+12V/40A and +24V/1.7A), totaling 480W of power. Its rugged construction and advanced protections (overvoltage, overcurrent, short circuit) ensure reliable operation in harsh environments, while a compact design (5.1 cm x 20.3 cm x 15.2 cm) enables easy integration into industrial control panels. The PW482-10 is ideal for applications requiring high-current stability, such as manufacturing lines, energy infrastructure, and process control systems.

6. Selection Recommendations
- Power Requirements: Ensure total load ≤ 480W (12V: 40A max; 24V: 1.7A max).
- Environment: Choose the extended temperature model (-20°C to +70°C) for outdoor or extreme-duty use.
- Redundancy: Deploy parallel modules for critical systems (e.g., dual PW482-10 units for 960W total power).
- Compatibility: Verify voltage/current needs match device specifications (e.g., 12V for actuators, 24V for sensors).
7. Installation and Usage Notes
-
Wiring: Use AWG 10–12 cables for 12V outputs; separate power and signal cables to minimize noise.
-
Ventilation: Maintain 10cm clearance around the module for cooling; avoid moisture and dust.
-
Grounding: Follow NEC/CE standards for protective grounding to prevent ESD.
-
Maintenance: Inspect terminals quarterly; replace after 7–10 years (or per Yokogawa guidelines).
